Risk levelMedium

0–100, higher is better. How it is calculated

The website sdn.cz currently presents an extremely minimalistic content state, displaying only a simple 'OK' message with no additional metadata, forms, or business information. The domain is registered since 2009 with a reputable Czech registrar, indicating a legitimate and stable registration history. However, the lack of visible content or policies suggests the site may be a placeholder or under development. The technical infrastructure cannot be fully assessed due to the minimal HTML content, but no WAF or blocking mechanisms are detected. Security posture is weak given the absence of HTTPS confirmation and security headers. Privacy compliance is non-existent on the visible site. Overall, the site lacks business credibility signals and user engagement features.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Due to the absence of business-related content, no clear market positioning, business model, or key services can be identified. The domain age and registrar suggest a Czech-based entity, but no company name or contact details are present. There is no evidence of partnerships, subsidiaries, or certifications. The site does not currently support business intelligence insights beyond domain registration data.

Security posture

The security posture is minimal and cannot be fully evaluated. No HTTPS or SSL configuration details are provided, and no security headers are detected. There is no evidence of vulnerability disclosure, incident response contacts, or security policies. The site does not demonstrate compliance with GDPR or other data protection frameworks. This represents a significant risk if the site is intended for public or business use.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure user connections.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and inform users.
  3. Publish contact information and incident response channels to improve trust and security readiness.
  4. Enhance website content with metadata, business descriptions, and navigation to improve user experience and SEO.
  5. Deploy security headers and conduct vulnerability assessments to strengthen security posture.

Key observations

  1. Website content is extremely minimal, only returning 'OK' in the body.
  2. No metadata, no forms, no scripts, no external links detected in the provided HTML.
  3. No privacy, cookie, or terms of service policies found.
  4. No contact information or business details visible on the site.
  5. No security headers or HTTPS information available from the provided data.
  6. WHOIS data indicates a stable domain with no privacy protection.
  7. No evidence of advertising, analytics, or tracking technologies.
  8. Website appears to be either a placeholder or a minimal status page.
Technical notes

Notes

The website's technical footprint is minimal, with no detectable scripts, frameworks, or CMS. The HTML is basic and lacks meta tags or SEO optimizations. Performance and mobile optimization cannot be assessed but are likely poor given the minimal content. Hosting provider and platform details are not available. The site appears to be a simple status or placeholder page without modern web technologies.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
